Sure. The more important thing is to understand why you should be skeptical of such things in general; but in this case, it's also easy to debunk the specific claims, because the numbers don't even work out the way he claims.
Carl Munck says that Stonehenge originally had 60 stones in the circle, counting uprights and lintels. He then multiplies this by 360 to get 21,600 and says that this factors into the precise latitude of Stonehenge, 51 degrees 10 minutes 42.353 seconds. That sounds pretty good, except that the center of Stonehenge is at 51 degrees 10 minutes 43.84 seconds. And if you multiply these together, you get 22,358.4. Now divide this by 360 degrees, and you get 62. Not 60! So I guess the ancient druids got it wrong, they should have used 62 stones. Or maybe Munck didn't account for continental drift? Either way, the thing that he says is an exact match -- is actually not a match at all.
In general, you can always make impressive-sounding numerical coincidences if you have enough numbers to work with. Stonehenge has 30 uprights and 30 lintels in the circle, 10 uprights and 5 lintels in the horseshoe. So you could just as well use 60, 30, 10, 5, 15, 40 (total uprights), 35 (total lintels), 75 (total stones), or 76 (counting the heel stone). And throw in 360 degrees in a circle, 365 days in a year, 28 days in a month, 24 hours in a day, 7 classical planets, etc., and pretty soon you've got hundreds of numbers to play with, combined in hundreds of thousands of ways. If you're clever, you can probably make them match your telephone number. If you fudge the numbers a little bit (like the latitude of Stonehenge), it's even easier. If you take the 76 total Stones in Stonehenge, multiply by 365 days in a year, and divide by 7 classical planets, you get 3963. This very special number is the radius of the Earth in miles! Does it mean that the builders of Stonehenge used miles and knew the precise radius of the Earth? No! It only means that I tried putting numbers together until I got a set that worked out. Exactly the same thing Carl Munck did.
Response to additional details:
I don't know where you got your latitude; you can verify on Google Maps, Bing, etc. that the center of the circle is at 43.8 seconds, not 42 seconds. Again, this is the center of the circle, not the street address. In any case, the larger point remains that given enough unrelated numbers, you can always put them together in such a way that there appears to be a deep connection between them.
